The N8122WU is an enablement feature for ST high power automotive-cell based products. The device is designed to work as both a gate turn-on device for SCRs and as a driver for high-power power switches. It is the first device in the industry that combines the functions of an SCR gate driver and a power switch driver into a single package. The combination of the two functions allows for more efficient energy management and enables higher power density in automotive-cell based applications.

The N8122WU is specifically suitable for the automotive-cell-based products that need a power switch with a high-voltage rating, a robust electrical operating capability, and an efficient energy management. The device is designed to provide resilience to EMI interference and to act as a driver for an SCR-based system. The device is also designed to work as both an SCR gate driver and a power switch driver, making it ideal for applications that need both functions.

A patented gate driver circuit is embedded in the logic die, ensuring that the SCR and the power switch are safely turning on and off. The gate driver monitors the voltage on the anode side of the SCR and power switch and provides a relay-like function to ensure fast switching action. The logic section includes an internal oscillator that can operate at up to 10 MHz, making it suitable for high switching speeds and accurate pulse waveforms. The various packages of the N8122WU range in size from 5 to 10 pins, which suit different application requirements in terms of I/O and power requirements.

The N8122WU is able to provide a wide operating voltage range, from 6 V to 80 V, making it suitable for high power applications. The device can handle a peak current of up to 700 A, allowing for high power performance, and it is also able to manage up to 30 mW of power dissipation, making it suitable for higher power applications. The N8122WU is also designed to operate over a temperature range of -40°C to 150°C, making it suitable for a variety of industrial applications.

The key advantages of the N8122WU are that it is a size optimized device that combines an SCR gate driver and a power switch driver into one package. This consolidated design makes it an ideal product for automotive-based applications that require reliable and efficient operation. Its low power design makes it suitable for a variety of automotive applications and its wide operating temperature range makes it suitable for industrial applications. The high power ratings of the device make it suitable for high power applications, while the small packages make it suitable for space-constrained applications.
